This demo is currently running **XTTS v2.0.3**
XTTS is a text-to-speech model that lets you clone voices into different languages.
This is the same model that powers our creator application Coqui Studio as well as the Coqui API. In production we apply modifications to make low-latency streaming possible.
There are 16 languages.
